An Optimal Control Framework to Address the Relationship between Water Resource Management and Water-Borne Health Impacts: Focus on the Texas Lower Rio Grande Valley AgEcon
Leidner, Andrew J.; Lacewell, Ronald D.; Rister, M. Edward; Sturdivant, Allen W..
The objective of this study is develop a theoretical model that can evaluate two types of public health expenditures on water-borne health risks: water-related municipal services, an ex ante preventative measure against water-borne contamination, and medical treatment, an ex post treatment of the water-borne pollutant’s harmful effects on human health. The modeled community can allocate resources in either centralized-municipal water-services, point-of-use water-services, or medical intervention, with expenditures subject to a budget constraint. The movement of a water-borne illness through the community is modeled with a susceptible-infected-susceptible (SIS) disease framework. An optimization framework is developed, including a statement of the...

Biological Control of Giant Reed (Arundo donax): Economic Aspects AgEcon
Seawright, Emily K.; Rister, M. Edward; Lacewell, Ronald D.; Sturdivant, Allen W.; Goolsby, John A.; McCorkle, Dean A..
Arundo donax is a large, invasive weed consuming large quantities of water in the riparian area of the Texas Rio Grande Basin. With water availability a concern to the area, the USDA-ARS is investigating biological control agents to increase available water, creating a benefit to both the region’s economy and society in general.

Challenges and Opportunities for Water of the Rio Grande AgEcon
Rister, M. Edward; Sturdivant, Allen W.; Lacewell, Ronald D.; Michelsen, Ari M..
The Rio Grande has headwaters in Colorado, flows through New Mexico, and serves as the United States.–Mexico border in Texas, emptying into the Gulf of Mexico. Snow melt in Colorado and northern New Mexico constitutes the water river supply for New Mexico and the El Paso region, whereas summer monsoonal flow from the Rio Conchos in Mexico and tributaries, including the Pecos River, provides the Rio Grande flow for southern Texas. The region is mostly semiarid with frequent long-term drought periods but is also characterized by a substantial irrigated agriculture sector and a rapidly growing population. International treaties and interstate compacts provide the rules for allocation of Rio Grande waters between the United States and Mexico and among...

Economic Implications of Conventional Water Treatment Versus Desalination: A Dual Case Study AgEcon
Rogers, Callie; Sturdivant, Allen W.; Rister, M. Edward; Lacewell, Ronald D.; Harris, Bill L..
Most municipalities use conventional treatment to produce potable water. Historically, desalination has not been economically feasible, but technological advancements warrant a new analysis. This study analyzes the costs of two Texas municipal facilities producing water using the above technologies based on Capital Budgeting-NPV analysis combined with annuity equivalents.

Effect of Agricultural Activity on River Water Quality: A Case Study for the Lower Colorado River Basin AgEcon
Adusumilli, Naveen C.; Lacewell, Ronald D.; Rister, M. Edward; Woodard, Joshua D.; Sturdivant, Allen W..
This case study investigates the effect of a change in cropping pattern involving expanded acres of crops for biofuel feedstock, on the discharge of nutrients to rivers. Annual data from 1968-2008 on stream flow, cropped acres, and precipitation for Wharton County, Texas are used. A positive impact of increased corn acreage over this period on river discharge is identified.

Identifying Economies of Size in Conventional Surface Water Treatment and Brackish-Groundwater Desalination: Case Study in the Rio Grande Valley of Texas AgEcon
Boyer, Christopher N.; Rister, M. Edward; Sturdivant, Allen W.; Lacewell, Ronald D.; Harris, Bill L..
Two primary potable water-treatment technologies used in South Texas include conventional surface-water and reverse-osmosis (RO) desalination of brackish-groundwater. As the region's population continues to grow, municipalities are searching for economical means to expand their water supplies. Economies of size for both technologies are an important consideration for future expansion decisions.

Seawater Desalination for Municipal Water Production AgEcon
Leidner, Andrew J.; Lacewell, Ronald D.; Rister, M. Edward; Woodard, Joshua D.; Sturdivant, Allen W.; White, Jacob M..
This paper examines the optimal allocation of several inputs in the context of seawater desalination by reverse osmosis (RO) as a source of municipal (or commercial or industrial) water. A cost-minimization model is developed, a production function is estimated, and sensitivity analyses are conducted using the optimization model to investigate the effect of environmental conditions and economic factors on the optimal input portfolio and the cost of operating a modeled seawater desalination facility. The objectives of this paper are to better understand the effect on the seawater desalination facility’s costs and input portfolio from changes in water quality, membrane lifespan, daily operations schedule, and energy prices. Findings include that lower...

STRATEGIC AGRIBUSINESS OPERATION REALIGNMENT IN THE TEXAS PRISON SYSTEM AgEcon
McCarl, Bruce A.; Rister, M. Edward; Ward, Ruby A.; Long, Charles R.; McCorkle, Dean A.; Ziari, Houshmand A.; Conner, J. Richard; Sturdivant, Allen W.; Thompson, Troy N..
Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating departments are considered. Methodology includes a firm systems operation model combined with capital budgeting and an integer programming based investment model. Results indicate the resources realize a positive return as a whole, but some enterprises are not using resources profitably. The integer investment model is found to be superior for investigating whether to continue multiple interrelated enterprises.
